Appendix 4 Connection with servo amplifiers
Appendix 4.1 Connection of SSCNET cables
As the SSCNET cables or termination connector is different depending on the servo
amplifiers, refer to the following connection example.
The SSCNET cables and termination connector used in the connection example are
any of the models shown in the following table.
When absolute position detection control is executed, installed battery (MR-BAT/
A6BAT) to servo amplifier.
